All those houses are lined with small cages. To give a sense of scale, the 5 slightly larger houses on the top of the screen each have 10 cages on either side of ~32 square meters. So you are looking at hundreds and hundreds of individual enclosures.

This is a place of literally industrial scale and with all the question marks around it, those areal photos do not look good.
